The SSD1963 datasheet says there are 2 modes that it support: Parallel RGB with 18/24 bits per pixel, and Serial RGB with 8 bit port. The TFT_eSPI User Setup 50 (parallel) has 8-bit parallel interface indeeded, maybe it’s a bit outdated or the word ‘parallel’ is misleading. So for proper initialization I think you need to look for experiences and solutions for this display.
